Vorbis - Apr 2007 - Vorbis decoder chip on SparkFun

I'm open to flames if this has already been posted.

As of April 17th, SF listed a new Ogg Vorbis decoder chip that is 
seriously listing for $10 USD. I'm excited. I think I'll buy a couple 
and integrate them into an IR streaming project I've been tinkering with.

Looks to me as if VLSI has taken a few shortcuts too much with this 
chip. The decoder does not implement the complete Vorbis specification 
and the chip is only capable of a sample rate < 46kHz if the USB 
connectivity is required. If you still find it useful and need a larger 
batch, the price from the manufacturer is as low as 4USD in quantities 
above 500pc.

"Maximum window size for an Ogg Vorbis ?le is 8192, however only
window sizes upto 4096 are in active use with
sample rates not exceeding 48 kHz.
Sample rates above 46875 Hz are played back at 46875 Hz. There are no
sample rate restrictions for lower sample
rates: non-standard sample rates can be played back without a
performance penalty."

A little bit unfortunate. Oh well.. pretty cool in any case.
